After many many months of researching, I've decided to go with the DSC-P150 due to the size, image quality, compactness and features. Just have two questions:

1. Any suggestions on the best place to buy it? I'm a little leary of some of these lesser known online retailers, particularly for something like a camera that may need service or return. Is there a place that you can recommend online that has a good balance of price and service? Or am I better off buying in store from a Ritz Camera or such and trying to negotiate some price break?

2. Wondering about the difference between Memory Stick Pro cards. Considering a 512 MB card. Is there any performance advantage (speed, etc) between the Sony, Lexar and SanDisk brands? Or are all MS Pro cards the same? Any features to look for? I know the Pro is faster than the regular memory stick, and I believe the Duo is just smaller but same performance. Is there any round up review of Memory Sticks out there somewhere that compares them? All I can seem to find is individual reviews of cards, but no round up comparisons.
Thanks,
Alex

Before buying from Ritz, I suggest you look at the Bizrate results and compare with B &amp; H and !7th St Photo. I know where my money wouldn't go. As regards memory, it is academic to consider writing speeds with a camera such as this. With an SLR with fast shutter speeds yes, but this is a fun point and press, not a serious sports photography tool. I reckon, especially with flash, the camera takes more time to recycle than the memory to write!

I have 2x256MB SanDisk Memory Stick Pro and 1x256MB Sony Memory Stick Pro and I cannot notice the difference between the performance of the two on my W1. I don't think it's worth paying extra for the Extreme/Ultra II/Extreme III.
